Deployment in React 19

Deploying React 19 applications involves building optimized assets and publishing them to a hosting platform. Follow these steps and best practices:

Build Process

• Use vite build, next build, or npm run build to generate production-ready assets.
• Review build output for errors and warnings.
• Minify and optimize assets for performance.

Deployment Platforms

• Static hosting: Vercel, Netlify, GitHub Pages, Firebase Hosting.
• Traditional servers: Nginx, Apache, Docker containers.
• Cloud platforms: AWS S3 + CloudFront, Azure Static Web Apps, Google Cloud Storage.

Example: Deploy to Vercel

1. Push your code to GitHub.
2. Connect your repository to Vercel.
3. Set build command to vite build or next build and publish directory to dist or .next.
4. Configure environment variables in Vercel dashboard.

CI/CD Setup

• Use GitHub Actions, GitLab CI, or similar for automated builds and deployments.
• Example workflow:
  • Install dependencies
  • Run tests
  • Build assets
  • Deploy to target platform

Asset Optimization

• Enable gzip or Brotli compression on the server.
• Use image optimization tools (e.g., ImageMagick, Squoosh).
• Set proper cache headers for static assets.

Troubleshooting

• Check build logs for errors.
• Verify environment variables are set correctly.
• Ensure correct base path in config for subfolder deployments.
